Module eth_types::sign_types

secp256k1 signature types and helper functions.

Structs

• SECP256K1_Q
  Secp256k1 Curve Scalar. Reference: Section 2.4.1 (parameter n) in “SEC 2: Recommended Elliptic Curve Domain Parameters” document at http://www.secg.org/sec2-v2.pdf
• SignData
  Signature data required by the SignVerify Chip as input to verify a signature.

Functions

• biguint_to_32bytes_le
  Convert a BigUint into 32 bytes in little endian.
• ct_option_ok_or
  Helper function to convert a CtOption into an Result. Similar to Option::ok_or.
• pk_bytes_le
  Return the secp256k1 public key (x, y) coordinates in little endian bytes.
• pk_bytes_swap_endianness
  Return a copy of the serialized public key with swapped Endianness.
• recover_pk
  Recover the public key from a secp256k1 signature and the message hash.
• sign
  Do a secp256k1 signature with a given randomness value.
